Asl 2.5mm Single Cable Green [metre]

Asl 2.5mm Single Cable Green (metre): Dedicated Earthing Conductor

Single-core cables are fundamental building blocks in electrical installation, used extensively for earthing connections within buildings, control panels, and equipment . This 2.5mm² single cable, available cut to length per metre, features a stranded copper conductor insulated with high-quality green PVC, specifically intended for protective earth and bonding applications where reliable earthing is essential.

The 2.5mm² conductor size is one of the most commonly used for earthing conductors and general wiring, offering an excellent balance of current capacity and flexibility. By offering this cable per metre, you can order precisely what your project requires without waste.

Asl 2.5mm Single Cable Green (metre): Key Specifications

Asl 2.5mm Single Cable Green (metre): Conductor Construction

The conductor is manufactured from plain annealed copper, chosen for its excellent electrical conductivity and ductility . The stranded construction consists of multiple fine copper wires twisted together, typically 7 strands of 0.67mm diameter for Class 2 stranded conductors or 50 strands of 0.25mm diameter for flexible Class 5 conductors, depending on the specific manufacturer and flexibility requirements .

This stranding offers several advantages:

• Flexibility: Easier to bend and route through conduit and trunking compared to solid conductors

• Vibration Resistance: Less prone to work-hardening and breaking in applications subject to movement

• Termination: Provides better contact area in screw terminals and earth clamps

• Handling: Easier to strip and prepare for connection

• Quality: Made with high-purity copper conductor for optimal performance

Asl 2.5mm Single Cable Green (metre): PVC Insulation

The green PVC insulation serves multiple critical functions :

Electrical Insulation: Provides excellent dielectric strength, preventing electrical leakage and ensuring safe isolation of the protective conductor where required.

Mechanical Protection: Protects the copper conductor from abrasion, impact, and damage during installation and service .

Colour Identification: The green insulation provides clear visual identification as a dedicated protective earth conductor. This is distinct from green/yellow striped cable which is also used for earthing, but plain green is specified for certain applications.

Environmental Resistance: PVC offers good resistance to moisture, chemicals, and UV exposure (when installed within appropriate containment). The materials used are cadmium-free and contain no silicone .

Temperature Rating: Rated for continuous operation up to 70°C, suitable for normal operating conditions in buildings .

Flame Retardant: PVC insulation is flame retardant, meeting safety standards for electrical installations .

Asl 2.5mm Single Cable Green (metre): Current Ratings

The current-carrying capacity of 2.5mm² cable depends on installation method :

These ratings are typical and may vary based on ambient temperature, grouping with other cables, and specific installation conditions. The maximum DC resistance of the conductor at 20°C is approximately 7.41-7.98 Ohm/km depending on stranding configuration . Reference should be made to the current edition of wiring regulations for final sizing.

Asl 2.5mm Single Cable Green (metre): Applications

This versatile single-core cable is suitable for numerous earthing and general wiring applications :

Earthing Conductors: Used as protective earth conductors in lighting circuits, power circuits, and final sub-circuits where a separate earth wire is required.

Supplementary Bonding: Ideal for supplementary bonding connections in bathrooms, kitchens, and other locations requiring additional protection.

Switch Drops: Suitable for wiring between ceiling roses and wall switches where an earth conductor is required.

Conduit Wiring: Ideal for drawing into conduit systems in commercial and industrial installations where individual insulated conductors are required for protected and fixed installation .

Control Panels: Used for internal wiring of control panels, distribution boards, and electrical enclosures where earth connections are needed.

Lighting Circuits: Suitable for use in or on light fittings and inside appliances, switchgear, and control gear .

General Wiring: Intended for use in semi-flush exposed conduits and embedded conduits as well as in closed installation ducts, and for the internal wiring of appliances and apparatus.

Asl 2.5mm Single Cable Green (metre): Why Buy Per Metre?

Purchasing this cable by the metre offers several practical advantages:

Cost-Effective: Buy exactly what you need for your specific project. No waste and no unused cable left coiled in your toolbox.

Project-Specific: Perfect for small jobs like earthing a single socket or replacing a bonding connection. Ordering per metre gives you complete control over quantities.

No Storage Issues: Avoid storing bulky coils of cable. Order precisely for your current requirements.

Flexible Quantities: Need 2 metres for one job and 7 metres for another? Order exactly per metre.

Asl 2.5mm Single Cable Green (metre): Installation Considerations

Conduit and Trunking: This cable is designed for installation within conduit, trunking, or other approved containment systems that provide mechanical protection . It is suitable for installation on or under plaster or in similar enclosed systems . Not suitable for direct laying in cable ladders and cable trays, except as a potential equalization cable .

Bending Radius: The minimum bending radius should be observed to prevent damage to the conductor or insulation. Typically 4 times the cable diameter for fixed installations .

Stripping: Use appropriate cable stripping tools to remove insulation without nicking or damaging the copper conductor strands.

Termination: Ensure conductors are correctly terminated in suitable terminals or earth clamps, with no stray strands exposed. The correct torque should be applied for the terminal type.

Derating: When multiple cables are bunched together, derating factors apply to the current-carrying capacity. Consult wiring regulations for guidance.

Temperature Range: Suitable for fixed installation from -30°C to +80°C, with active operation from 5°C to 70°C .

Asl 2.5mm Single Cable Green (metre): Voltage Rating

The 450/750V voltage rating indicates :

• 450V: Voltage to earth (phase to neutral/earth)

• 750V: Voltage between phases

This makes the cable suitable for standard single-phase and three-phase installations up to 750V, covering all normal domestic and commercial applications. The test voltage is 2.5 kV .

Asl 2.5mm Single Cable Green (metre): Important Notes

Continuous Length: When you order multiple metres, you will receive one continuous length of cable, not multiple separate pieces. For example, ordering 5 metres supplies a single 5-metre length.

Cut to Order: Each length is cut from a full reel specifically for your order per metre. This may add a small processing time to dispatch.

Returns: Due to hygiene and safety reasons, cut cable cannot be returned unless faulty. Please measure your requirements carefully before ordering per metre.

Asl 2.5mm Single Cable Green (metre): Quality and Compliance

This cable is manufactured to meet rigorous international standards:

• BS 6004: British Standard for PVC-insulated cables for electric power and lighting

• HD 21 / EN 50525-2-31: Harmonised European standard for PVC-insulated cables

• CE Marking: Indicates compliance with relevant European directives

• RoHS Compliance: Free from hazardous substances

• SVHC Free: Compliant with substances of very high concern regulations

• Flame Retardant: Meets EN 60332-1-2 / IEC 60332-1-2 standards

Asl 2.5mm Single Cable Green (metre): Measuring Your Needs

To determine how much cable you require:

1. Earthing Connections: Measure from the earth terminal to the bonding point, allowing for routing around obstacles.

2. Switch Drops: Measure from the ceiling rose position to the switch position, allowing for vertical drops and horizontal runs.

3. Control Wiring: Measure panel layouts and add extra for neat routing and termination.

4. Always add extra for connections at each end—typically 100-150mm per termination to allow for comfortable working.

5. Allow for routing around corners, through walls, and along cable trays.

When installed correctly within appropriate containment and in accordance with current wiring regulations, Asl 2.5mm Single Cable Green, available per metre, provides a safe, reliable, and clearly identified earthing solution for fixed wiring in residential, commercial, and industrial applications.
